High-density linkage map construction and QTL analyses for fiber quality, yield and morphological traits using CottonSNP63K array in upland cotton (Gossypium hirsutum L.)

Table 8 Clusters containing multiple QTLs from same trait category (fiber quality or yield). QTL mapping study involved the RIL population of cross NC05AZ06 × NC11–2091 genotyping with Cotton 63K SNP array. Phenotypic traits were evaluated in the field at Central Crops Research Station, Clayton, NC in years 2016 and 2017
